Background:
Cognitive impairment is a common non-motor symptom in Multiple Sclerosis (MS), negatively affecting autonomy and Quality of Life (QoL). Innovative rehabilitation strategies, such as semi-immersive virtual reality (VR) and computerized cognitive training (CCT), may offer advantages over traditional cognitive rehabilitation (TCR), particularly in terms of engagement, specificity, adaptability, and ecological validity. This study aimed to compare the efficacy of semi-immersive VR, CCT using the ERICA platform, and TCR on cognitive outcomes and depressive/anxiety symptoms in individuals with MS.
Methods:
Eighty-seven patients with MS and mild to moderate cognitive impairment were randomly assigned to three groups: VR-based training, CCT, or TCR. Each group underwent 24 individual sessions delivered regularly three times per week over 8 weeks. Neuropsychological assessments were conducted at baseline (T0) and post-intervention (T1), evaluating information processing speed (SDMT), memory (SRT, SPART), executive functions (WLG), emotional status (BDI, HRS-A), and QoL (MSQOL-54).
Results:
All groups showed significant improvements in most cognitive and depressive (BDI)/anxiety symptoms (HRS-A) after the intervention. However, the VR group demonstrated significantly greater gains in executive functions, working memory, and QoL (MSQOL-54 Physical and Mental Composite scores) compared to both the CCT and TCR groups (p < 0.001). While the CCT group showed selective improvements in mood and working memory, its overall efficacy did not significantly differ from that of TCR.
Conclusions:
Semi-immersive VR represents an effective and engaging approach to cognitive rehabilitation in MS, likely due to its capacity to deliver multisensory, adaptive, and ecologically valid stimulation. Nonetheless, a tailored hybrid model integrating VR with conventional and computer-based strategies may further optimize outcomes and support functional independence in individuals with MS.
